Flutter 我正在为搜索和 comments 购物车页面创建布尔条件

我正在为search and review cart页面设置bool条件，然后我面临这3个我试图解决但未成功的错误(容器上的前2个错误//预计会找到"，".//无法将元素类型"bool"分配给列表类型"Widget".)以及文本小部件上的第二个小部件(预期会找到"]")

bool isBool = false;
  SigleItem(this.isBool);



 isBool ==false  Container( //Expected to find ','. //The element type 'bool' can't be assigned to the list type 'Widget'.
                  margin: const EdgeInsets.only(right: 15),
                  padding: const EdgeInsets.symmetric(horizontal: 10),
                  height: 35,
                  decoration: BoxDecoration(
                    border: Border.all(color: Colors.grey),
                    borderRadius: BorderRadius.circular(30),
                  ),

                      ),
